Not recognising my gas

Yesterday i transfered ETH from BSC network. So i received succesfully in Metamask adding the ETH tolken. Now i want to use that for Swap or send them back to binance and i cant do it cos it says “not enough gas” as it doesnt recognise the ETH i have in MEtamask.

Please need help!
Thank you.
